Horizontal Impedances for Radially Inhomogeneous Viscoelastic Soil Layers
(1987)A study of the dynamic impedances of horizontally excited, radially inhomogeneous, infinite viscoelastic soil layers with a circular hole, and of piles embedded in a medium represented by such layers is made considering ... 
Hybrid Control of SeismicExcited Nonlinear and Inelastic Structural Systems
(1991)Refined versions of the instantaneous optimal control algorithms for nonlinear or inelastic systems are proposed. Their advantage is that the control vector is determined directly from the measured response state vector ... 
Hysteretic Models for Cyclic Behavior of Deteriorating Inelastic Structures
(1999)Two hysteretic models (a polygonal model and a smooth model) for inelastic behavior of macromodels of structural components are developed. These models can simulate the deteriorating behavior of strength, stiffness, and ... 
IDARC Bridge: A Computational Platform for Seismic Damage Assessment of Bridge Structures
(1998)This report presents the theoretical background of a computer platform for threedimensional inelastic analysis of bridge structures. The program adapts and extends some of the component and damage models of the existing ... 
IDARC Version 3.0: A Program for the Inelastic Damage Analysis of Reinforced Concrete Structures
(1992)This report summarizes significant modeling and program enhancements to the computer code, IDARC (see NCEER870008) for inelastic damage analysis of reinforced concrete framewall structures. As described here, IDARC is ... 
IDARC2D, Version 4.0: A Computer Program for the Inelastic Damage Analysis of Buildings
(1996)This report summarizes recent enhancements to the IDARC computer program which has been and continues to be developed for the analysis of earthquakeinduced damage to inelastic reinforced concrete structures. This report ... 
IDARC: Inelastic Damage Analysis of Reinforced Concrete Frame  ShearWall Structures
(1987)The needs for analytical tools to support experiments and design processes led the authors to develop a computer program for the Inelastic Damage Analysis of Reinforced Concrete FrameShear Wall Structures, IDARC. The ... 
Impact Assessment of Selected MCEER Highway Project Research on the Seismic Design of Highway Structures
(1999)This report details the independent review of the results obtained from each of the studies conducted under the fouryear MCEER research project on the "Seismic Vulnerability of New Highway Construction" and assesses the ... 
Inelastic Response of Reinforced Concrete Structures with Viscoelastic Braces
(1993)The addition of viscoelastic braces in structures for vibration reduction was proposed and implemented in the past decade in metal models or fullscale structures. Viscoelastic braces provide energy dissipation, while the ... 
Instantaneous Optimal Control for Linear, Nonlinear and Hysteretic Structures  Stable Controllers
(1991)Recently, instantaneous optimal control algorithms have been proposed and developed for applications to control seismicexcited linear, nonlinear and hysteretic structural systems. In particular, these control algorithms ... 
Instantaneous Optimal Control Laws for Tall Buildings Under Seismic Excitations
(1987)A critical review of classical optimal control algorithms is made with respect to the specific application of structural control under seismic loads. With the earthquake ground acceleration being the major source of ... 
Instantaneous Optimal Control with Acceleration and Velocity Feedback
(1990)In the experimental demonstration of aseismic control systems, difficulties were encountered in the measurement of the displacement response of the structure. During earthquake ground motions, both the building and the ... 
Investigation of Seismic Response of Buildings with Linear and Nonlinear Fluid Viscous Dampers
(1997)This report presents results of the first systematic experimental study of nonlinear fluid viscous dampers. Earthquake simulation tests have been performed on one and threestory model structures with and without linear ... 
The Island of Guam Earthquake of August 8, 1993
(1993)A magnitude 8.0 earthquake occurred 30 kilometers off the southern coast of the pacific island of Guam on Sunday, August 8, 1993. Moderate damage to structures and lifelines occurred throughout the island. Injuries were ... 
Issues in Earthquake Education
(1992)This volume offers 17 short presentations on various aspects of earthquake education in the elementary schools. Major topics considered include: 1) meeting the needs of culturally diverse school populations; 2) curricular ...
